Description

Technical Field

[0001] This utility model pertains to the straightening of welded steel structures, specifically a general-purpose straightening device for welded steel structures. Background Technology

[0002] When steel structures are welded, the high temperature during welding and the low temperature after welding can easily generate tension at the weld joint. This tension can cause the angle of the welded steel structure to change, thus affecting its normal use.

[0003] To solve this problem, the existing method involves first opening the welded steel structural components, then fixing some of them. After cooling, the tension is eliminated, maintaining the angle and effectively preventing it from changing due to tension. However, existing methods for fixing and straightening steel structures often only fix steel structures welded to right angles, failing to fix steel structures with acute angles, thus limiting their applicability. Utility Model Content

[0004] This utility model provides a general-purpose straightening device for welding steel structures to overcome the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A general-purpose straightening device for welding steel structures includes a base plate, a side plate hinged to the right side of the top surface of the base plate, one end of an electric telescopic rod hinged to the top surface of the base plate, the other end of the electric telescopic rod hinged to the bottom surface of the side plate, an arc-shaped rod fixedly connected to the front side of the base plate, an arc-shaped groove provided on the arc-shaped rod, the arc-shaped groove being located on a circle with the hinge point of the side plate and the base plate as the center, an indicator arrow that swings along the arc-shaped groove fixedly connected to the front of the side plate, and angle scale lines provided along the arc-shaped groove on the arc-shaped plate.

[0007] In this application, the angle of the acute-angled steel structure will decrease under tension after welding. Therefore, our main goal is to increase the included angle back to its initial angle. When using this application, firstly, the angle of the welded steel structure to be corrected is determined as needed. Then, the electric telescopic rod is activated. The electric telescopic rod drives the side plate to swing along its hinge point. The swing of the side plate causes the indicator arrow to rotate along the hinge point within the arc-shaped groove. After rotating to the determined position, the extension of the electric telescopic rod is stopped to ensure that the angle remains unchanged. Then, the deformed steel structure is pulled apart using tools to make the included angle the required angle. This structure is then inserted into the steel structure so that the bottom plate and side plate contact the corresponding components of the steel structure. Therefore, with the support of the electric telescopic rod, the angle can be effectively prevented from retracting again, and after complete cooling, the angle is guaranteed not to change again, thus achieving the correction of the steel structure.

[0008] Preferably, the bottom surface of the side plate extends downward along the vertical center line of the side plate with a truncated cone that is wider at the top and narrower at the bottom, and the movable end of the telescopic rod is hinged to the bottom surface of the truncated cone. The truncated cone allows the electric telescopic rod to better support the side plate.

[0009] Preferably, the bottom surface of the base plate and the top surface of the side plates are both longitudinally provided with sliding grooves. Two sliders are fitted into the sliding grooves, and the sliders are fixedly connected to clamping plates. The sliders located in the same sliding groove are driven by a driving device to move synchronously in opposite directions. The synchronous movement of the sliders in opposite directions under the drive device can drive the clamping plates to move synchronously, thereby clamping the corresponding steel structure and preventing the steel structure from tilting on the side plates and base plates, thus achieving better correction of the steel structure.

[0010] Preferably, the driving device includes a fixed plate fixedly mounted at the end of the slide groove. Two sliders located within the same slide groove have threaded holes with opposite threads. Lead screws are threaded into these holes, and the two lead screws are coaxial and fixedly connected. A round rod is coaxially fixedly connected to the end of one lead screw, passing through the fixed plate and rotatably connected to the fixed plate via a bearing. Rotating the lead screw causes the sliders to rotate. Since the sliders slide within the slide groove, the rotation of the lead screw causes the sliders to move. Because the threads on the sliders are opposite, the sliders move synchronously in opposite directions.

[0011] Preferably, the bottom surface of the base plate and the opposite surface of the clamping plate are both anti-slip surfaces. The anti-slip surfaces can effectively prevent relative sliding between the base plate and the corresponding steel structure, thereby ensuring the correction effect.

[0012] Preferably, the system also includes a horizontal plate, with a vertical plate vertically connected to one side of the top surface of the horizontal plate. A slide rail is vertically fixed on the vertical plate, and a moving block slides on the slide rail. A left clamping telescopic rod is vertically connected to the moving block. A right clamping telescopic rod, opposite to the left clamping telescopic rod, is horizontally fixed to the right side of the top surface of the horizontal plate. When the steel structure is placed on the horizontal plate, the left clamping telescopic rod abuts against the left side of the base plate, and the right clamping telescopic rod abuts against the right side of the steel structure, thereby further preventing relative sliding between the base plate and the corresponding steel structure.

[0013] The beneficial effects of this utility model are as follows: The use of this application can not only correct steel structures with acute angles, but also steel structures with acute angles of different angles, thereby increasing the scope of application of the equipment.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] A general-purpose straightening device for welding steel structures, such as Figures 1-3 As shown. It includes a base plate 1 and a horizontal plate 10. A side plate 2 is hinged to the right side of the top surface of the base plate 1. One end of an electric telescopic rod 3 is also hinged to the top surface of the base plate 1. The other end of the electric telescopic rod 3 is hinged to the bottom surface of the side plate 2. An arc-shaped rod is fixedly connected to the front side of the base plate 1. An arc-shaped groove 4 is opened on the arc-shaped rod. The arc-shaped groove 4 is located on a circle with the hinge point of the side plate 2 and the base plate 1 as the center. An indicator arrow 5 that swings along the arc-shaped groove 4 is fixedly connected to the front of the side plate 2. An angle scale line is opened on the arc-shaped plate along the arc-shaped groove 4.

[0022] A vertical plate 11 is vertically connected to one side of the top surface of the horizontal plate 10. A slide rail 12 is vertically fixed on the vertical plate 11. A moving block is slidably fitted on the slide rail 12. A left clamping telescopic rod 13 is vertically connected to the moving block. A right clamping telescopic rod 14, which is opposite to the left clamping telescopic rod 13, is horizontally fixed to the right side of the top surface of the horizontal plate 10.

[0023] In this application, the angle of the acute-angled steel structure will decrease under tension after welding. Therefore, our main goal is to increase the included angle back to its initial angle. When using this application, the steel structure is placed on the horizontal plate 10. First, the angle of the welded steel structure to be corrected is determined as needed. Then, the electric telescopic rod 3 is activated. The electric telescopic rod 3 drives the side plate 2 to swing along its hinge point. The swing of the side plate 2 causes the indicator arrow to rotate along the hinge point within the arc-shaped groove 4. After rotating to the determined position, the extension of the electric telescopic rod 3 is stopped to ensure that its angle remains unchanged. Then, the deformed steel structure is pulled apart using tools to make the included angle the required angle. This structure is then inserted into the steel structure, so that the bottom plate 1 and the side plate 2 contact the corresponding components of the steel structure. Therefore, with the support of the electric telescopic rod 3, the angle can be effectively prevented from retracting again, and after complete cooling, the angle is guaranteed not to change again, thus achieving the correction of the steel structure. The left clamping telescopic rod is pressed against the left side of the base plate 1, and the right clamping telescopic rod 14 is pressed against the right side of the steel structure, which can further prevent relative sliding between the base plate 1 and the corresponding steel structure.

[0024] The bottom surface of the side plate 2 extends downward along the vertical center line of the side plate 2, forming a truncated cone 15 that is wider at the top and narrower at the bottom. The movable end of the telescopic rod is hinged to the bottom surface of the truncated cone 15. The truncated cone 15 allows the electric telescopic rod 3 to better adjust the truncated cone support of the side plate 2.

[0025] Both the bottom surface of the base plate 1 and the top surface of the side plate 2 are longitudinally provided with sliding grooves 6. Two sliders 7 are fitted into the sliding grooves 6, and the sliders 7 are fixedly connected to clamping plates 8. The sliders 7 located in the same sliding groove 6 are driven by a driving device to move synchronously in opposite directions. The synchronous movement of the sliders 7 in opposite directions under the drive of the driving device can drive the clamping plates 8 to move synchronously, thereby clamping the corresponding steel structure and preventing the steel structure from tilting on the side plate 2 and the base plate 1, thus achieving better correction of the steel structure.

[0026] The driving device includes a fixed plate fixedly mounted at the end of the slide groove 6. Two sliders 7 located in the same slide groove 6 have threaded holes with opposite threads. Lead screws 9 are threaded into these holes, and the two lead screws 9 are coaxial and fixedly connected. A round rod is coaxially fixedly connected to the end of one lead screw 9. The round rod passes through the fixed plate and is rotatably connected to the fixed plate via a bearing. Rotating the lead screw 9 causes the sliders 7 to rotate. Since the sliders 7 are slidably fitted within the slide groove 6, the rotation of the lead screw 9 causes the sliders 7 to move. Because the threads on the sliders 7 are opposite, the sliders 7 move synchronously in opposite directions.

[0027] The bottom surface of the base plate 1 and the opposite surface of the clamping plate 8 are both anti-slip surfaces. The anti-slip surfaces can effectively prevent relative sliding between the base plate 1 and the corresponding steel structure, thereby ensuring its correction effect.

[0028] The use of this application can not only correct steel structures with acute angles, but also steel structures with acute angles of different degrees, thereby increasing the scope of application of the equipment.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
